Les surfaces des moules d’injection sont polies \u00e0 l’aide de divers outils pour obtenir une finition miroir, un processus connu sous le nom de polissage. Les outils couramment utilis\u00e9s pour le polissage des moules \u00e0 injection<\/a> sont les pierres \u00e0 aiguiser, le papier de verre, les p\u00e2tes \u00e0 polir, les roues en laine, etc. Pour obtenir des r\u00e9sultats de polissage de haute qualit\u00e9, il est conseill\u00e9 d’opter pour des outils de polissage et des produits auxiliaires de premi\u00e8re qualit\u00e9 tels que les pierres \u00e0 aiguiser, le papier de verre et la p\u00e2te \u00e0 polir diamant\u00e9e. <\/p>\n\n

<\/div>\n\n

Le choix de la technique de polissage d\u00e9pend de l’\u00e9tat de surface apr\u00e8s les \u00e9tapes de traitement initiales telles que l’usinage, l’\u00e9lectro\u00e9rosion, le meulage, etc. Comment polir les moules d’injection ? Le processus g\u00e9n\u00e9ral de polissage m\u00e9canique comprend les \u00e9tapes suivantes : <\/p>\n\n

1. Polissage grossier<\/h3>\n\n

Apr\u00e8s le fraisage, l’\u00e9lectro\u00e9rosion, le meulage ou des processus similaires, la surface peut \u00eatre polie \u00e0 l’aide d’une machine de polissage de surface rotative ou d’une meuleuse \u00e0 ultrasons avec une vitesse de rotation de 35 000 \u00e0 40 000 tours\/minute. Une m\u00e9thode courante consiste \u00e0 \u00e9liminer la couche blanche d’\u00e9lectro\u00e9rosion \u00e0 l’aide d’une meule d’un diam\u00e8tre de \u03a63mm et de WA #400. Ensuite, le meulage manuel avec des pierres \u00e0 aiguiser est effectu\u00e9 \u00e0 l’aide d’une bande de pierre \u00e0 aiguiser lubrifi\u00e9e ou refroidie avec du k\u00e9ros\u00e8ne. La s\u00e9quence typique comprend #180 ~ #240 ~ #320 ~ #400 ~ #600 ~ #800 ~ #1000. Pour gagner du temps, de nombreux fabricants de moules commencent directement par le num\u00e9ro 400. <\/p>\n\n

2. Polissage semi-fini<\/h3>\n\n
<\/div>\n\n

Le polissage semi-fini utilise principalement du papier de verre et du k\u00e9ros\u00e8ne. La s\u00e9quence du papier de verre comprend #400 ~ #600 ~ #800 ~ #1000 ~ #1200 ~ #1500. Il convient toutefois de noter que le papier de verre #1500 ne convient qu’\u00e0 l’acier tremp\u00e9 (52HRC et plus), et non \u00e0 l’acier pr\u00e9tremp\u00e9, car il peut provoquer des br\u00fblures superficielles sur ce dernier. <\/p>\n\n

<\/div>\n\n

3. Polissage fin<\/h3>\n\n

Le polissage fin fait principalement appel \u00e0 la p\u00e2te \u00e0 polir diamant\u00e9e. Lorsqu’elle est m\u00e9lang\u00e9e \u00e0 un disque de polissage, la s\u00e9quence de polissage typique consiste en 9\u03bcm (#1800) ~ 6\u03bcm (#3000) ~ 3\u03bcm (#8000). Une p\u00e2te abrasive diamant\u00e9e de 9\u03bcm et une roue en tissu de polissage peuvent \u00e9liminer efficacement les poin\u00e7ons laiss\u00e9s par les papiers de verre #1200 et #1500. Vient ensuite le polissage au feutre collant et \u00e0 la p\u00e2te abrasive diamant\u00e9e, avec une s\u00e9quence de 1\u03bcm (#14000) ~ 1\/2\u03bcm (#60000) ~ 1\/4\u03bcm (#100000). <\/p>\n\n

Les processus de polissage des moules d’injection n\u00e9cessitant une pr\u00e9cision sup\u00e9rieure \u00e0 1\u03bcm (y compris 1\u03bcm) sont r\u00e9alis\u00e9s dans une salle de polissage propre au sein de l’atelier de traitement des moules. Pour une pr\u00e9cision maximale, un environnement d’une propret\u00e9 irr\u00e9prochable est indispensable. La poussi\u00e8re, la fum\u00e9e, les pellicules ou les gouttelettes peuvent compromettre la surface m\u00e9ticuleusement polie obtenue apr\u00e8s des heures de travail. <\/p>\n","protected":false},"excerpt":{"rendered":"
